Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573748, here are decompositions:

  • 137 + 33573611 = 33573748
  • 167 + 33573581 = 33573748
  • 269 + 33573479 = 33573748
  • 317 + 33573431 = 33573748
  • 347 + 33573401 = 33573748
  • 359 + 33573389 = 33573748
  • 389 + 33573359 = 33573748
  • 401 + 33573347 = 33573748

Showing the first eight; more decompositions exist.
